Abstract

fetched live from OpenAlex

The air in which we human survive is being increasingly affected by greenhouse gas emissions since global industries are developing fast and more human activities occur.High attention thus is being paid to how greenhouse gas influences the environment by national governments,which has become an international environmental issue.It is known that Perfluorocarbon compounds(PFCs) are released from primary aluminium production.And researches on PFCs has been done in the United States,Australia,Canada etc.since 1990s.However,not much work has been done in our country.In this paper,negative impacts and evaluation methods of PFCs,the mechanism of PFCs' coming into being during aluminium production and its emitting,and techniques taken by foreign manufacturers for solution of PFCs problem is presented,which could be helpful to domestic aluminium industry as a good reference for PFCs emission.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
